The invention relates to a middle fuselage high-speed transport vehicle for a large passenger aircraft. The fuselage high-speed transport vehicle is characterized by comprising a gooseneck (1), a gooseneck lifting hydraulic cylinder (2), a middle vehicle frame (3), a tail lifting hydraulic cylinder (4), a lifting swing arm (5) and a back vehicle frame (6), wherein the front end of the gooseneck (1) is hinged to a traction vehicle head through a traction pin, the cylinder body end of the gooseneck lifting hydraulic cylinder (2) is fixedly arranged on the gooseneck (1), a piston rod is hinged to the front part of the middle vehicle frame (3), the back end of the gooseneck (1) is connected with the front end of the middle vehicle frame (3) through a pin shaft, the front end of the back vehicle frame (6) is connected with the back end of the middle vehicle frame (3) through the lifting swing arm (5), a piston rod of the tail lifting hydraulic cylinder (4) is hinged to the lifting swing arm (5), and the other end of the tail lifting hydraulic cylinder (4) is fixedly connected with the back vehicle frame (6). The middle fuselage high-speed transport vehicle has the advantages that the structure is compact and flexible, the working is stable, the operation is simple and convenient, and the safety is high.
Description
technical field [0001] The invention relates to a high-speed medium-body transport vehicle for a large passenger aircraft, which can ensure the safety and stability of the medium-body of the aircraft and the appearance of the fuselage during long-distance high-speed transportation. It belongs to the field of transportation of large aircraft parts. Background technique [0002] The C919 large passenger aircraft is my country's first domestically produced large aircraft. Due to the long distance between the assembly plant and the final assembly plant, during the long-distance high-speed transportation of the medium fuselage, the transport vehicle may encounter bumpy roads, slopes, speed bumps, and toll charges. Road conditions such as roadblocks, impacts, gravel and other foreign objects, and severe weather such as strong winds may generate a large overturning moment on the transport vehicle, which will seriously threaten the safety of the fuselage of the aircraft during long-d...
